    Abstract: A semiconductor die is disclosed. The semiconductor die includes a semiconductor body, a metallization over part of the semiconductor body and including a noble metal at a top surface of the metallization, a bondwire having a foot bonded to the top surface of the metallization, and a sealing material covering the foot of the bondwire, the top surface of the metallization, and one or more areas outside the top surface of the metallization where oxide and/or hydroxide-groups would be present if exposed to air. The sealing material adheres to the foot of the bondwire and the one or more areas outside the top surface of the metallization where the oxide and/or hydroxide-groups would be present if exposed to air.

    Abstract: A method includes forming a first electrically conductive layer on a first side of a dielectric insulation layer, forming a structured mask layer on a side of the first electrically conductive layer that faces away from the dielectric insulation layer, forming at least one trench in the first electrically conductive layer, said at least one trench extending through the entire first electrically conductive layer to the dielectric insulation layer, forming a coating which covers at least the bottom and the side walls of the at least one trench, and removing the mask layer after the coating has been formed.
